Oxygen-containing and amino groups functionalized polymeric carbon nitride atomically-thin porous nanosheets with hydrophilic surfaces strong Lewis basicity are designed synthesized for enhanced photocatalytic H<sub>2</sub>evolution.
Targeting activation functionalized catalyst of Ru-loaded ultrathin layered double hydroxides is developed to realize photothermal CO2 methanation in flow-type system. Capability targeting and simultaneous H2 over this enables achieve ≈230 mol h−1 m−2 (irradiation area) maximum yield rate for CH4 production. As a service our authors readers, journal provides supporting information supplied by the authors. Such materials are peer reviewed may be re-organized online delivery, but not...
An in-depth spectroscopic study on blue luminescent carbon dots highlights the role of surface chemistry in their physicochemical properties.
Oxide dispersion strengthened (ODS) steels with different contents of zirconium (denoted as 16Cr ODS, 16Cr-0.3Zr ODS and 16Cr-0.6Zr ODS) were fabricated to investigate the effects Zr on strengthening mechanism Al-alloyed steel. Electron backscatter diffraction (EBSD) results show that mean grain size could be decreased by addition. Transmission electron microscope (TEM) indicate addition increase number density but decrease diameter inter-particle spacing oxide particles. Furthermore, it is...
Different atmospheric gas molecules (e.g., N2, O2, CO2, H2O, CO, NO, NO2, NH3, and SO2) are absorbed on the pristine hexagonal boron arsenide (BAs) through density functional theory calculations. For each molecules, various adsorption positions were considered. The most stable depended position, energy, charge transfer, work function. SO2 had best shortest distance for BAs surface in molecule, a certain amount of transfer. calculation function was important exploring possibilities adjusting...
Novel graphitic carbon nitride/KTaO 3 (g‐C N 4 /KTaO ) nanocomposite photocatalysts have been successfully synthesized via a facile and simple ultrasonic dispersion method. Compared to either g‐C or KTaO , the composite show significantly increased photocatalytic activity for degradation of Rhodamine B (RhB) under visible light irradiation. The performance could be attributed enhanced photogenerated charge carrier separation capacity. Moreover, it is observed that ∙ main active species in...
Synergistic effect of nanostructuration and boron doping allows sub-bandgap electron acceptor states in diamond materials to be controlled.
An Au/SrTiO<sub>3</sub> catalyst with basic properties (Au/SrTiO<sub>3</sub>–urea) was firstly reported to be efficient for the dehydrogenation of secondary alcohols at room temperature.
Carbon dots (CDs) exhibit outstanding physicochemical properties that render them excellent materials for various applications, often occurring in an aqueous environment, such as light harvesting and fluorescence bioimaging. Here we characterize the electronic structures of CDs water molecules dispersions using situ X-ray absorption spectroscopy. Three types with different core (amorphous vs graphitic) compositions (undoped nitrogen-doped) were investigated. Depending on CD structure, ionic...
Polymeric carbon nitride (PCN) is a promising class of materials for solar-to-chemical energy conversion. The increase the photocatalytic activity PCN often achieved by incorporation heteroatoms, whose impact on electronic structure remains poorly explored. This work reveals that local strongly altered doping with sulfur and iron using X-ray absorption spectroscopy (XAS) resonant inelastic scattering (RIXS). From XAS at nitrogen K-edges, atoms are found to mostly affect atoms, in contrast...
In this work we provide a proof of principle for theoretical methodology to identify functionalisation patterns in oxidised carbon 2D nanomaterials. The is based on calculating large number X-ray absorption spectra individually excited atoms different chemical environments using density functional theory. Since each resulting spectrum gives fingerprint the local electronic structure surrounding atom, may relate pattern that atom up desired neighbourhood radius. These pattern-specific are...
Abstract Many applications of TiO 2 nanoparticles, such as photocatalytic water splitting or remediation, occur in aqueous environment. However, the impact solvation on electronic structure remains unclear because only few experimental methods are currently available to probe nanoparticle–water interface. Soft X‐ray absorption spectroscopy has been extensively used characterize materials, but so far vacuum conditions. Here, oxygen K edge and titanium L characterization nanoparticles measured...
Brain barrier is both a protective permeability hurdle and limitation site where therapeutic agents are excluded to enter the target region. Designing drug vehicle overcome this notorious bottle challenging. Herein, we construct stimuli-responsive self-assembled nanovesicle that delivers water-soluble drugs prevent efflux transport of brain barriers by responding endogenously occurring signals in Alzheimer's disease (AD) microenvironment. Once vesicles accumulated intracerebrally,...
